UNTTED STATES PATENT EricEa NATHAN BARNEY, OF BERGEN POINT, NEW JERSEY, ASSIGNOR TO THE BARNEY DUMPING BOAT COMPANY, OF SAME PLACE.

DUMPlNG-SCOW.

SPECIFICATION forming part of Letters Patent No. 271,298, dated January 30, 1883. Application filed May 26, 1882. (No model.)

To all whom fit may concern: 1

Beit known that I, NATHAN BARNEY, of Bergen'Point, in the county ot' Hudson 'and State of New Jersey, have invented certain new and useful Improvements in Dumping- Boats, of which the following is a specitication.

My invention relatesto dumping boats or scow's which are severally composed of two ioats or pontons, which are hinged at their upper and out/er longitudinal edges, so that they may be brought together to receive the load, and when released will swing downward, and outward, so as to dump the load between them and afford a clear opening from end to end ot' the boat or scow. In such boats or scows the two iloats or pontons have been connected at opposite ends ofthe boat or scow by sectors geared together, or connected by other means, so as to cause the iloats or pontons to move together in opening and closing; and the principal object of my invention is to provide an effective and simple means for holding the iioats or pontons together to receive and carry the load, for controlling or retarding their opening movement, which is apt to be too rapid, because of the great weight ot' the load and the momentum acquired in opening, and for holding them in their outermost position after the load is (lumped and while the boat or scow is being towed ahead, so that the water can have a clear passage between the floats or pontons, and thus wash out all matters which otherwise might adhere to the iloat or pontons.

To this end my invention consists in the combination, with two ioats or pontons, of a slideway extending transversely tothe same, sliding bars connected one with each loat or ponton, arranged iu an approximately horizontal position and adapted to move in said yslideway, and means for clamping said bars together' or against a suitable guide or stationary beam or resistance-piece, so that they cannot move one upon another or in opposite directions, as they must do to allow the iioats or pontons to swing or move toward or from each other. eft'ectivethe sliding bars may be provided with shoulders, which are made to engage with each In order to render them more other by the clamping of said bars; and the means for clamping of the bars may consist ofa cam on a vertical shaft acting' upon a yoke which is pressed against one ot said bars.

The invention also consists in the combination, with the two hinged floats or pontons, pairs of sliding bars arranged parallel with each other transversely above the floats or pontons, and connected therewith, and acam and cam-shaft for clamping the bars of each pair, of a shaft extending longitudinally of the iioats or pontons, and gearing connecting said longitudinal shat't with said calnshaf'ts for turning them in unison. The invention also consists in the combination, with two floats or pontons hinged as above described, and geared sectors connecting them, ot' projections on the sides ot' the sectors and spring or elastic cushions, upon whichthe said projections strike as the iioats or pontons approach the end of their outward movement away from each other, as hereinafter fully described.

In the accompanying drawings, Figure l represents a plan of a boator scow embodyingmy invention. Fig. 2 represents a transverse sec tion of the boat er scow upon the dotted line :r Fig. l. Fig. 3 represents a similar section upon the dotted line y y, Fig. 1. Fig. 4 represents a transverse section ot' a pair of sliding bars, which are connected with the floats or pontons, and the mechanism for clamping them, upon a larger scale. Fig. represents a horizontal section ofthe parts shown in Fig. et, upon the same scale.

Similar letters ot' reference designate corresponding parts in` all the figures.

A A designate the two floats or pontons, which together form the scow or boat, and which may be constructed in any suitable manner to secure the desired strength and buoyancy.

At or near each end of the boat or scow isa y platform or deck portion, B, and intermediately between the ends is a third platform or deck portion, B.

The floats or pontons are secured or hinged to the platforms or deck portions B B by hinges or pivots a along their upper and outer longitudinal edges, so that they may swing ICO freely downward and outward when released, and the upper or load-supporting surfaces of the doats or pontons are inclined downward and inward toward each other at an angle of about forty-tive degrees, (450,) as clearly shown in Figs. 2 and 3.

Near each end of the two floats or scows A A they are provided with sectors C, w-hich are geared together and cause the tloats or pontons to move in unison toward and from each other.

'lhe sectors are provided on their sides with studs or projections b, and as the iioats or pontonsreach the end oftheir outward movement the projections strike upon stops c, made of india-rubber springs or other elastic or spring material, and which form cushions for checking the movement of the floats or pontons.

In each platform or deck portion B B is a slideway, B2, extending transversely to the boat or scow,and in such slideway isarran ged a pair of sliding bars, D D', which are parallel with each other. The'bars D D are connected with the two floats .or pon tons by rods, as best shown in Fig. 2, the bar D being connected by a rod, E, with the float or ponton A, and the bar D being connected by a similar rod, E', with the iioat or ponton A. It will therefore be seen that when the floats or pontons swing outward the bars D D' will be moved or slid through the rods E E in opposite directions, and if said bars are locked or held against movement the iioats or pontons cannot swing on their hinges either toward or from each other.

Adjacent to each pair of bars D D is a vertical shaft, F, carrying at its lower end a cam, d, and said cam is arranged in an open yoke or shoe, e, which it presses against one of said bars .when the shaft is rotated. On the opposite side of the bars D D from the shaft F is a beam or wall, l7",against which one of said bars is pressed, and by the joint action of thecam d and the beam or resistance-piece fthe bars are clamped securely together and are held against movement one upon the other.

Upon their adjacent faces the bars D D may have shoulders, g, which engage with each other, as shown best in Fig. 5, when the floats or pontons are closed or brought together, and the bars are pressed together or clamped, and by this means the iioats or pontons are held against swinging outward in a very secure manner. y

In order to enable `all lthe vertical camshafts to be turned together, I provide a shaft, G, extending longitudinally of the boat or scow, and provided with a hand-wheel, G', whereby it may be turned.

Upon the shaftG are bevel pinions or wheels, h, which engage with similar pinions, t', on the cam-shafts F, and effect the turning of the latter, and by this means all the pairs of bars D D may be clamped together simultaneously and simultaneously released.

`When the boat is to receive its load the several pairs of bars D D are clamped together, and the floats or pontons are lheld together by them until it is desired to dump theload. The shafts F are then turned to release the bars, and the Weight of the load will cause the floats or pontons to swing outward or apart, and the bars of each pair will move or slide one upon another. It is desirable that the oats or pontons should be prevented from swinging outward too rapidly, and this I effect by not entirely releasing the sliding bars,

Qbut by pressing them together with such force as to create considerable friction by their movement, which will of course retard or regulate the swinging movement of thefloats or pontons.

When the Hoa-ts or pontons reach the end of their outward movement the shaft G is turned so as to clamp all the pairs ot' bars D D', and the floats or pontons are thus held apart,while the boat or scow is towed slightly ahead. The water now has a clear passage between the floats or pontons, and the towing ahead of the boat or scow leaves all the light iioating garbage behind, and Washes olf the oats or pontons any material whiclrwould otherwise stay upon them. The sliding bars D D" are then released, and the oats or pontons are free to swing inward by their buoyancy and.

will swing inward close together.

It will be seen that the pairs of sliding bars form a very simple and effective means for holding or locking the floats or pontons together or apart, and for regulating or controlling the swinging movement of the floats or pontons.

In order to prevent the longitudinal movement of either oat or ponton independently ofthe other in case of collision or striking a dock or other obstacle, I provide one oat with a lug,j, which fits between lugs j on the other float, as clearly shown in Fig. 1.
